| 1 | Preliminary results pertaining to coseismic displacement and preseismic strain accumulation of the Lushan M_S7.0 earthquake,as reflected by GPS surveying显示文摘This paper presents the coseismic displacement and preseismic deformation fields of the Lushan MS7.0 earthquake that occurred on April 20,2013.The results are based on GPS observations along the Longmenshan fault and within its vicinity.The coseismic displacement and preseismic GPS results indicate that in the strain release of this earthquake,the thrust rupture is dominant and the laevorotation movement is secondary.Furthermore,we infer that any possible the rupture does not reach the earth’s surface,and the seismogenic fault is most likely one fault to the east of the Guanxian-Anxian fault.Some detailed results are obtainable.(1)The southern segment of the Longmenshan fault is locked preceding the Lushan earthquake.After the Wenchuan earthquake,the strain accumulation rate in the southeast direction accelerates in the epicenter of the Lushan earthquake,and the angle between the principal compressional strain and the seismogenic fault indicates that a sinistral deformation background in the direction of the seismogenic fault precedes the Lushan earthquake.Therefore,it is evident that the Wenchuan MS8.0 earthquake accelerated the pregnancy of the Lushan earthquake.(2)The coseismic displacements reflected by GPS data are mainly located in a region that is 230 km(NW direction)×100 km(SW direction),and coseismic displacements larger than 10 mm lie predominantly in a100-km region(NW direction).(3)On a large scale,the coseismic displacement shows thrust characteristics,but the associated values are remarkably small in the near field(within 70 km)of the earthquake fault.Meanwhile,the thrust movement in this70-km region does not correspond with the attenuation characteristics of the strain release,indicating that the rupture of this earthquake does not reach the earth’s surface.(4)The laevorotation movements are remarkable in the 50-km region,which is located in the hanging wall that is close to the earthquake fault,and the corresponding values in this case correlate with the attenuation characteristics of the strain release. | WU YanQiang JIANG ZaiSen WANG Min CHE Shi LIAO Hua LI Qiang LI Peng YANG YongLin XIANG HePing SHAO ZhiGang WANG WuXing WEI WenXin LIU XiaoXia | 2013 | Chinese Science Bulletin2013，58，28： | 33 |
| 2 | Induction of Th1-Type Immune Response by Chitosan Nanoparticles Containing Plasmid DNA Encoding House Dust Mite Allergen Der p2 for Oral Vaccination in Mice显示文摘This study was to prepare the chitosan-pDer p 2 nanoparticles and to investigate the effect of chitosan-DNA nanoparticles on immune response in mice by oral delivery of chitosan-DNA nanoparticles. The nanoparticles were synthesized by complexing chitosan with plasmid DNA. The DNA was fully complexed into chitosan-DNA nanoparticles,suggesting a 100% encapsulation efficiency. Chitosan-DNA complex renders a significant protection of the plasmid. No effect on cell viability was observed in both cell types and average cell viability over 100% was obtained. Oral gene delivery with chitosan-DNA nanoparticles can generate a higher level expression of gene in vivo. Oral chitosan-pDer p 2 nanoparticles in BALB/c mice can induce IFN-γ in serum and prevent subsequent sensitization of Th2 cell-regulated specific IgE responses. The data indicate that the oral administration of chitosan-pDer p 2 nanoparticles results in the expression of Der p 2 in the epithelial cells of both stomach and small intestine and the induction of Th1-type immune response. | Guoping Li Zhigang Liu Bin Liao Nanshan Zhong | 2009 | Cellular & Molecular Immunology2009，6，1： | 10 |
| 3 | Therapeutic Effects of DNA Vaccine on Allergen-Induced Allergic Airway Inflammation in Mouse Model显示文摘Vaccination with DNA encoding Dermatophagoides pteronyssinus group 2 (Der p 2) allergen previously showed its effects of immunologic protection on Der p 2 allergen-induced allergic airway inflammation in mice. In present study, we investigated whether DNA vaccine encoding Der p 2 could exert therapeutic role on allergen-induced allergic airway inflammation in mouse model and explored the mechanism of DNA vaccination in asthma specific-allergen immunotherapy. After sensitized and challenged by Der p 2, the BALB/c mice were immunized with DNA vaccine. The degrees of cellular infiltration were scored. IgE levels in serum and IL-4/IL-13 levels in BALF were determined by ELISA. The lung tissues were assessed by histological examinations. Expressions of STAT6 and NF-κB in lung were determined by immunohistochemistry staining. Vaccination of mice with DNA vaccine inhibited the development of airway inflammation and the production of mucin induced by allergen, and reduced the level of Der p 2-specific IgE level. Significant reductions of eosinophil infiltration and levels of IL-4 and IL-13 in BALF were observed after vaccination. Further more, DNA vaccination inhibited STAT6 and NF-κB expression in lung tissue in Der p 2-immunized mice. These results indicated that DNA vaccine encoding Der p 2 allergen could be used for therapy of allergen-induced allergic airway inflammation in our mouse model. | Guoping Li Zhigang Liu Nanshan Zhong Bin Liao Ying Xiong | 2006 | Cellular & Molecular Immunology2006，3，5： | 9 |
| 4 | Analysis of genetic diversity and population structure of Chinese yak breeds (Bos grunniens) using microsatellite markers显示文摘Nine Chinese yak breeds (Maiwa, Tianzhu White, Qinghai Plateau, Sibu, Zhongdian, Pali, Tibetan High Mountain, Jiulong, and Xin-jiang) and Gayal were analyzed by means of 16 microsatellite markers to determine the level of genetic variation within populations, genetic relationship between populations, and population structure for each breed. A total of 206 microsatellite alleles were observed. Mean F-statistics (0.056) for 9 yak breeds indicated that 94.4% of the genetic variation was observed within yak breeds and 5.6% of the genetic variation existed amongst breeds. The Neighbor-Joining phylogenetic tree was constructed based on Nei's standard genetic dis-tances and two clusters were obtained. The Gayal separated from the yaks far away and formed one cluster and 9 yak breeds were grouped together. The analysis of population structure for 9 yak breeds and the Gayal showed that they resulted in four clusters; one clus-ter includes yaks from Tibet Autonomous Region and Qinghai Province, one cluster combines Zhongdian, Maiwa, and Tianzhu White, and Jiulong and Xinjiang come into the third cluster. Pali was mainly in the first cluster (90%), Jiulong was mainly in the second cluster (87.1%), Zhongdian was primarily in the third cluster (83%), and the other yak breeds were distributed in two to three clusters. The Gayal was positively left in the fourth cluster (99.3%). | Guixiang Zhang Weisheng Chen Ming Xue Zhigang Wang Hong Chang Xu Han Xinjun Liao Donglei Wang | 2008 | Journal of Genetics and Genomics2008，35，4： | 8 |
| 5 | Global cultivated land mapping at 30 m spatial resolution显示文摘Cultivated land is one of the most important types of land cover in the global mapping of land cover, and its variation influences economic development, food security, and ecological environment protection. Existing products of global cultivated land mapping have a low resolution, and high spatial resolution products are in demand. This study uses global remote sensing image datasets in 2000/2010 with a spatial resolution of 30 m(Landsat TM/ETM+, HJ-1), MODIS 250 m NDVI time-serial data, and many types of reference data. An three-layer extraction method based on pixels, objects, and knowledge(POK) was adopted to ease cultivated land extraction in global-scale 30 m images, i.e., cultivated land classification based on pixel-scale multi-feature optimization, cultivated land automatic identification based on objects, and interactive object processing based on information service and priori knowledge. Global 30 m cultivated land mapping was accomplished for the two reference years(2000 and 2010), and statistical analysis was conducted on the data. Results showed that the total cultivated land area was 1.903 billion ha and 1.960 billion ha, respectively. Accuracy assessments showed that overall accuracy of global cultivated land mapping are higher than 92% for both the two reference years. The global cultivated land products in 2000/2010 developed in this research are superior to their international counterparts in terms of spatial resolution and classification accuracy. They also provide significant basic data on global food security, ecological environment supervision, and global change. | CAO Xin CHEN XueHong ZHANG WeiWei LIAO AnPing CHEN LiJun CHEN ZhiGang CHEN Jin | 2016 | Science China(Information Sciences)2016，59，12： | 8 |
| 6 | Sufficient and necessary conditions for Lyapunov stability of Lorenz system and their application显示文摘The sufficient and necessary conditions for Lyapunov stability of the zero equilibrium point of Lorenz system are discussed, and some brief criteria are presented for globally exponential stability, globally asymptotical stability and instability. Furthermore, the behavior of the non-zero equilibrium point of Lorenz system is also investigated, and several sufficient and necessary conditions are provided for locally exponential stability and instability. The established theorems in this paper develop and extend the existing achievements on Lyapunov stability of Lorenz system. In conclusion, by applying the obtained results, some less conservative feedback-control laws are derived to guarantee the globally exponential stability of the chaos control of Chen system, Lu¨ system, Yang-Chen system and Yu-Xia Li system. | LUO Qi LIAO XiaoXin ZENG ZhiGang | 2010 | Science China(Information Sciences)2010，53，8： | 8 |

| 8 | Chemical formation and source apportionment of PM_(2.5) at an urban site at the southern foot of the Taihang mountains显示文摘The region along the Taihang Mountains in the North China Plain(NCP) is characterized by serious fine particle pollution. To clarify the formation mechanism and controlling factors, an observational study was conducted to investigate the physical and chemical properties of the fine particulate matter in Jiaozuo city, China. Mass concentrations of the water-soluble ions(WSIs) in PM_(2.5) and gaseous pollutant precursors were measured on an hourly basis from December 1, 2017, to February 27, 2018. The positive matrix factorization(PMF) method and the FLEXible PARTicle(FLEXPART) model were employed to identify the sources of PM_(2.5). The results showed that the average mass concentration of PM_(2.5) was 111 μg/m^(3) during the observation period. Among the major WSIs, sulfate, nitrate, and ammonium(SNA) constituted 62% of the total PM_(2.5) mass, and NO_(3)^(-) ranked the highest with an average contribution of 24.6%. NH_(4)^(+) was abundant in most cases in Jiaozuo. According to chemical balance analysis, SO_(2)-4, NO_(3)^(-), and Cl^(-) might be present in the form of(NH_4)_(2)SO_4, NH_4NO_3, NH_4Cl, and KCl. The liquid-phase oxidation of SO_(2) and NO_(2) was severe during the haze period. The relative humidity and pH were the key factors influencing SO_(4)^(2-) formation. We found that NO_(3)^(-) mainly stemmed from homogeneous gas-phase reactions in the daytime and originated from the hydrolysis of N_(2)O_5 in the nighttime, which was inconsistent with previous studies. The PMF model identified five sources of PM_(2.5) : secondary origin(37.8%), vehicular emissions(34.7%), biomass burning(11.5%), coal combustion(9.4%), and crustal dust(6.6%). | Xiaoyong Liu Mingshi Wang Xiaole Pan Xiyue Wang Xiaolong Yue Donghui Zhang Zhigang Ma Yu Tian Hang Liu Shandong Lei Yuting Zhang Qi Liao Baozhu Ge Dawei Wang Jie Li Yele Sun Pingqing Fu Zifa Wang Hong He | 2021 | Journal of Environmental Sciences2021，33，5： | 5 |
| 9 | A multi-institutional retrospective study of hyperthermic plus intravesical chemotherapy versus intravesical chemotherapy treatment alone in intermediate and high risk nonmuscle-invasive bladder cancer显示文摘Objective:To compare the efficacy and safety of hyperthermic intravesical chemotherapy(HIVEC)and intravesical chemotherapy(IVEC)in patients with intermediate and high risk nonmuscle-invasive bladder cancer(NMIBC)after transurethral resection.Methods:We included 560 patients diagnosed with primary or recurrent NMIBC between April 2009 and December 2015 at 1 of 6 tertiary centers.We matched 364 intermediate or high risk cases and divided them into 2 groups:the HIVEC+IVEC group[chemohyperthermia(CHT)composed of 3 consecutive sessions followed by intravesical instillation without hyperthermia]and the IVEC group(intravesical instillation without hyperthermia).The data were recorded in the database.The primary endpoint was 2-year recurrence-free survival(RFS)in all NMIBC patients(n=364),whereas the secondary endpoints were the assessment of radical cystectomy(RC)and 5-year overall survival(OS).Results:There was a significant difference in the 2-year RFS between the two groups in all patients(n=364;HIVEC+IVEC:82.42%vs.IVEC:74.18%,P=0.038).Compared with the IVEC group,the HIVEC+IVEC group had a lower incidence of RC(P=0.0274).However,the 5-year OS was the same between the 2 groups(P=0.1434).Adverse events(AEs)occurred in 32.7%of all patients,but none of the events was serious(grades 3–4).No difference in the incidence or severity of AEs between each treatment modality was observed.Conclusions:This retrospective study showed that HIVEC+IVEC had a higher 2-year RFS and a lower incidence of RC than IVEC therapy in intermediate and high risk NMIBC patients.Both treatments were well-tolerated in a similar manner. | Qiang Ruan Degang Ding Bin Wang Chaohong He Xuequn Ren Zhenhua Feng Zhigang Pang Jin Wang Xiangliang Zhang Hongsheng Tang Jiahong Wang Qingjun He Ziying Lei Quanxing Liao Jiali Luo Shuzhong Cui | 2021 | Cancer Biology & Medicine2021，18，1： | 4 |
| 10 | Combustion synthesis and magnetic investigation of nanosized CoFe_2O_4显示文摘Nanosized Co spinel ferrite was prepared by a combustion method. The grain size of resultant ferrite can becontrolled by the reaction conditions. Magnetic investigation revealed that the products with an average grain size of 4 nm behave as superparamagnetic materials and have zero coercive force; whereas the samples with an average grain size of 85 nm (near the size of critical single domain) have the maximal coercive force. There were the negative magnetic intergrain interactions which became stronger when the grain size neared that of the single domain. | XU Zhigang, CHENG Fuxiang, ZHOU Biao, LIAO Chunsheng & YAN ChunhuaState Key Laboratory of Rare Earth Materials Chemistry and Applications, PKU-HKU Joint Laboratory on Rare Earth Materials and Bioin-organic Chemistry, Peking University, Beijing 100871, China | 2001 | Chinese Science Bulletin2001，46，5： | 4 |
| 11 | Qualitative and quantitative assessment of related substances in the Compound Ketoconazole and Clobetasol Propionate Cream by HPLC-TOF-MS and HPLC显示文摘Related substances in pharmaceutical formulations are associated with their safety, efficacy and stability. However, there is no overall study already published on the assessment of related substances in the Compound Ketoconazole and Clobetasol Propionate Cream. In this work, a reliable HPLC-TOF-MS qualitative method was developed for the analysis of related substances in this preparation with a quick and easy extraction procedure. Besides the active pharmaceutical ingredients, two compounds named ketoconazole impurity B′ optical isomer and ketoconazole impurity E were identified. Furthermore, a new HPLC method for qualitative and quantitative assessment on related substances and degradation products, which were found in the stability test, was established and validated. The single standard to determine multi-components method was applied in the quantitative analysis, which was an effective way for reducing cost and improving accuracy. This study can provide a creative idea for routine analysis of quality control of the Compound Ketoconazole and Clobetasol Propionate Cream. | Wenling Yang Xiaomei Yang Fanghua Shi Zhigang Liao Yongkun Liang Liangzhong Yu Ruixun Wang Qing Li Kaishun Bi | 2019 | Journal of Pharmaceutical Analysis2019，9，3： | 4 |
| 12 | Surpassing electrocatalytic limit of earth-abundant Fe^(4+)embedded in N-doped graphene for(photo)electrocatalytic water oxidation显示文摘Developing highly active,cost-effective,and environmental friendly oxygen evolution reaction(OER)electrocatalysts facilitates various(photo)electrochemical processes.In this work,Fe3N nanoparticles encapsulated into N-doped graphene nanoshells(Fe_(3)N@NG)as OER electrocatalysts in alkaline media were reported.Both the experimental and theoretical comparison between Fe_(3) N@NG and Fe_(3)N/NG,specifically including in situ Mossbauer analyses,demonstrated that the NG nanoshells improved interfacial electron transfer process from Fe_(3)N to NG to form high-valence Fe^(4+)ions(Fe^(4+)@NG),thus modifying electronic properties of the outer NG shells and subsequently electron transfer from oxygen intermediate to NG nanoshells for OER catalytic process.Meanwhile,the NG nanoshells also protected Fe-based cores from forming OER inactive and insulated Fe_(2)O_(3),leading to high OER stability.As a result,the as-formed Fe^(4+)@NG shows one of the highest electrocatalytic efficiency among reported Fe-based OER electrocatalysts,which can as well highly improve the photoelectrochemical water oxidation when used as the cocatalysts for the Fe_(2)O_(3) nanoarray photoanode. | Wenjia Xue Feng Cheng Menglu Li Wenjian Hu Congping Wu Bing Wang Kuowei Liao ZhenTao Yu Yingfang Yao Wenjun Luo Zhigang Zou | 2021 | Journal of Energy Chemistry2021，30，3： | 2 |
| 13 | Study on Network Security Architecture for Power Systems显示文摘The wide application of network technology in power systems brings not only convenience and flexibility but also security threats. An architecture of network security for power system was proposed in this study,which protected data and facilities from being attacked by outside users by means of firewall, security monitor and control system. Firewall was basically the first line of defense for the intranet; the security monitoring system was a kind of IDS (Intrusion Detection System), while security control system provided authentication, authorization,data-encrypted transmission and security management. This architecture provides various security services, such as identification, authentication, authorization, data integrity and confidentiality. | Chen Yan Li Zengzhi Liao Zhigang | 2005 | Electricity2005，16，3： | 2 |
| 14 | Influence of RNA interference on the mitochondrial subcellular localization of alpha-synuclein and on the formation of Lewy body-like inclusions in the cytoplasm of human embryonic kidney 293 cells induced by the overexpression of alphasynuclein显示文摘The specific and effective α-synuclein RNA interference (RNAi) plasmids, and the α-synuclein-pEGFP recombinant plasmids were co-transfected into human embryonic kidney 293 (HEK293) cells using the lipofectamine method. Using an inverted fluorescence microscope, α-synuclein proteins were observed to aggregate in the cytoplasm and nucleus. Wild-type α-synuclein proteins co-localized with mitochondria. Hematoxylin-eosin staining revealed round eosinophilic bodies (Lewy body-like inclusions) in the cytoplasm of some cells transfected with α-synuclein-pEGFP plasmid. However, the formation of Lewy body-like inclusions was not observed following transfection with the RNAi pSYN-1 plasmid. RNAi blocked Lewy body-like inclusions in the cytoplasm of HEK293 cells induced by wild-type α-synuclein overexpression, but RNAi did not affect the subcellular localization of wild-type α-synuclein in mitochondria. | Tao Chen Xiaoping Liao Guoqiang Wen Yidong Deng Min Guo Zhigang Long Feng Ouyang | 2012 | Neural Regeneration Research2012，7，2： | 2 |

| 19 | RNA interference blocking the apoptosis in HEK293 cells induced by overexpression of alpha-synuclein显示文摘BACKGROUND:Overexpression ofα-synuclein can induce cell apoptosis.RNA interference(RNAi) may block specific gene function and cause gene silencing. OBJECTIVE:To construct a specific and effective RNAi plasmid for theα-synuclein gene and investigate if RNAi can block apoptosis in HEK293 cells,induced by overexpression of wild-typeα-synuclein. DESIGN,TIME AND SETTING:A contrast experiment based on genetically engineered cytobiology was performed at the State Key Lab of Medical Genetics of China,Xiangya Medical College of Central South University,between October 2004 and October 2008. MATERIALS:HEK293 cells and pBSHH1 plasmid were provided by the State Key Lab of Medical Genetics of China;OligDNA sequence by Sagon Bioengineering Company,Shanghai; Lipofectamine 2000 by Invitrogen,USA;α-synuclein monoclonal antibody,Hoechst 33258,and MTT; by Sigma,USA;Horseradish peroxidase-coupled goat anti-rat IgG by KPL,USA;FACSan flow cytometry by BD,USA. METHODS:Four target sites were used to construct hairpin RNA pBSHH1 vectors-pSYNi-1, pSYNi-2,pSYNi-3 and pSYNi-4-which were cloned in the pBSHH1 plasmid.HEK293 cells were transfected using Lipofectamine 2000.In addition,a non-transfect group and a negative plasmid transfect group were established.The cultured HEK293 cells were processed as follows: transfection of blank plasmid(blank control group),transfection ofα-synuclein-pEGFP and RNAi negative vector(negative control group),and transfection ofα-synuclein-pEGFP and pSYNi-1 (transfection group).Cells in all groups were transfected with Lipofectamine 2000 for 48 hours. MAIN OUTCOME MEASURES:Expression ofα-synuclein mRNA and protein were detected by RT-PCR and Western blot.Cell morphology was observed under an inverted fluorescence microscope;cell viability was measured using MTT method;and cell apoptosis was determined with Annexin V-PE flow cytometry. RESULTS:α-synuclein mRNA and protein expressions were significantly decreased in the pSYNi-1 group when compared with the non-transfect and negative plasmid transfect groups(P<0.05).The expressions were partially decreased in the pSYNi-2 group,but there was no significant difference in the pSYNi-3 and pSYNi-4 groups.Hoechst staining indicated that cell nuclei were enlarged in the negative control group,coloring was not uniform,and chromatin was accumulated and appeared spot-like.The nucleus coloring was uniform in the transfection group compared to negative control group.Cell viability in the negative control group was significantly lower than blank control group with cell apoptosis being significantly increased(P<0.05).In comparison with negative control group, cell viability was significantly increased in the transfection group and cell apoptosis was significantly decreased(P<0.05). CONCLUSION:pSYNi-1 can inhibitα-synuclein gene expression and block apoptosis of HEK293 cells induced by overexpression of wild-typeα-synuclein. | Tao Chen Beisha Tang Xiaoping Liao Guoqiang Wen Xinxiang Yan Jifeng Guo Yuhu Zhang Feng Ouyang Zhigang Long Li Cao Jing Li | 2009 | Neural Regeneration Research2009，4，7： | 1 |
| 20 | Numerical simulation and data assimilation of the water-energy cycle over semiarid northeastern China显示文摘The default fractional vegetation cover and terrain height were replaced by the estimated fractional vegetation cover, which was calculated by the Normalized Difference Vegetation Index(NDVI) of Earth Observing System Moderate-Resolution Imaging Spectroradiometer(EOS-MODIS) and the Digital Elevation Model of the Shuttle Radar Topography Mission(SRTM) system. The near-surface meteorological elements over northeastern China were assimilated into the three-dimensional variational data assimilation system(3DVar) module in the Weather Research and Forecasting(WRF) model. The structure and daily variations of air temperature, humidity, wind and energy fields over northeastern China were simulated using the WRF model. Four groups of numerical experiments were performed, and the simulation results were analyzed of latent heat flux, sensible heat flux, and their relationships with changes in the surface energy flux due to soil moisture and precipitation over different surfaces. The simulations were compared with observations of the stations Tongyu, Naiman, Jinzhou, and Miyun from June to August, 2009. The results showed that the WRF model achieves high-quality simulations of the diurnal characteristics of the surface layer temperature, wind direction, net radiation, sensible heat flux, and latent heat flux over semiarid northeastern China in the summer. The simulated near-surface temperature, relative humidity, and wind speed were improved in the data assimilation case(Case 2) compared with control case(Case 1). The simulated sensible heat fluxes and surface heat fluxes were improved by the land surface parameterization case(Case 3) and the combined case(Case 4). The simulated temporal variations in soil moisture over the northeastern arid areas agree well with observations in Case 4, but the simulated precipitation should be improved in the WRF model. This study could improve the land surface parameters by utilizing remote sensing data and could further improve atmospheric elements with a data assimilation system. This work provides an effective attempt at combining multi-source data with different spatial and temporal scales into numerical simulations. The assimilation datasets generated by this work can be applied to research on climate change and environmental monitoring of arid lands, as well as research on the formation and stability of climate over semiarid areas. | WEN XiaoHang LIAO XiaoHan YUAN WenPing YAN XiaoDong WEI ZhiGang LIU HuiZhi FENG JinMing LU ShiHua DONG WenJie | 2014 | Science China Earth Sciences2014，57，10： | 1 |
